1. Prepare the cake batter

• Preheat your oven to 350°F (175°C). Grease and line two 9-inch cake pans with parchment paper.

• In a medium bowl, whisk together flour, cocoa powder, baking soda, and salt. Set aside.

• In a large mixing bowl, beat butter and sugar until light and fluffy.

• Add eggs one at a time, mixing well after each addition. Stir in vanilla extract.

2. Add wet and dry ingredients

• Mix in the buttermilk, alternating with the dry ingredients, starting and ending with the flour mixture.

• Stir in the vinegar, then add the green food coloring and mix until fully incorporated. Adjust color as needed.

3. Bake the cake

• Divide the batter evenly between the prepared cake pans.

• Bake for 28-30 minutes, or until a toothpick inserted in the center comes out clean.

• Allow the cakes to cool in the pans for 10 minutes before transferring them to a wire rack to cool completely.

4. Make the frosting

• In a large bowl, beat cream cheese and butter until smooth and creamy.

• Gradually add powdered sugar, mixing until fluffy.

• Stir in vanilla extract and add heavy cream as needed to reach a spreadable consistency.

5. Assemble and decorate

• Place one cake layer on a serving plate and spread a generous layer of frosting on top.

• Add the second cake layer and frost the top and sides evenly.

• Decorate with green sprinkles, white chocolate shavings, or edible gold dust for a festive touch.
